Module imageproc::integralimage
[−]
[src]
Functions for computing integral images and running sums of rows and columns.
Functions
column_running_sum |
Computes the running sum of one column of image, padded at the top and bottom. The padding is by continuity. Takes a reference to buffer so that this can be reused for all columns in an image. |
integral_image |
Compute the 2d running sum of a grayscale image. |
row_running_sum |
Computes the running sum of one row of image, padded at the beginning and end. The padding is by continuity. Takes a reference to buffer so that this can be reused for all rows in an image. |
sum_image_pixels |
Sums the pixels in positions [left, right] * [top, bottom] in F, where integral_image is the integral image of F. |
